The R-951 Residences are 3 new condominium units in a multifamily building with developed for sale. Certified under the Passive House standard, the super-insulated 5600SF building serves as a model for energy efficiency, excellent indoor air quality, and superior thermal comfort.  The developer targeted Passive House certification and net zero capable performance as a market differentiator, successfully selling two of the units before construction was even complete. The resulting building with three dwelling units includes a high performance building enclosure, design for passive solar gain, very high efficiency mechanical systems, and grid-tied photovoltaics. These performance attributes helped contribute to both media and buyer appeal. The building was also awarded 2nd place for the Multi-Family Building category at the 2015 PHIUS-PHAUS Passive Building Project Competition.
